`Specification of Letters Patent.

Patented Mar. 6, 1917.

To all whom it may concern: f

Be it known that I, CHARLES A. PERFECT, a citizen ofthe United States,residing at Sunbury,'in thecounty 'of Delaware and State of Ohio, haveinvented a new and useful Automatic Loader, of which the following is aspecification.'

The device forming the subject matter-of this application is adapted tobe employed for unloading f romvrailroad cars on a track, broken stone,gravel, sand, screenings or other loose material.

The invention aims to provide novel means for securing a reciprocationof a feeder, to provide novel means whereby the feeder and attendantparts may be adjusted, and to provide novel means whereby the materialis conveyed upwardly to a 'suitable re- It is within the province of thedisclosure to improve generally and to enhance the utility of devicesofv that type to which the present invention appertains.

With the above and other objects in view which will appear'as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details ofconstruction hereinafterdescribed and claimed, itv being understood that changes'in the preciseembodiment ofthe invention herein disclosed 'can be made'within thescope of what is claimed lwithout departing from the spirit of theinvention.

' In the accompanying drawings,

Figure 1l is a transverse sectional view showing an automatic loaderembodyingthe improvements hereinafter described, certain parts appearingin elevation;

Fig. 2 is an end elevation showing the re' ceiver and attendantmechanisms;

Fig. 3 is a cross section taken throughv the receiver on the line 3-3ofFig. 6;

Fig. 4 is a side elevation of the receiver; Fig. 5 is alongitudinalsection ofthe receiver; and.

Fig. 6 is a top plan of the receiver.

In the accompanying 'l drawings, the numeral 1 indicates a suitablesupport, such as a road bed, upholding cross ties 2,*carrying the rails3 of a track or tramway. Mounted on adjacent cross ties 2 are inclineddeflectors 4. When the material is dumped out of a car, the deliectorsdirect the material between the cross ties 2. Between the cross ties 2,a channel 5 is formed in the road bed 1, transversely of the rails 3,the channel 5'communieating with a pit 6 formed in the road bed l on oneside of the track rails lBeyond the pit 6 and to one side of thetrack 33 is a support 7.

receiver is located between the cross ties 2, and the material dumpedfromv a car is directed by the deflectors 4; into the receiver. The'receiver is a composite structure, and its construction will now be setforth.

The receiver embodies a pair of side bars 8 preferably in the form ofchannels, the side bars 8 being connectedby upwardly inclined Vcrossedbraces 9 and by transverse braces' 10. -The side Ibars 8 carry bolts 11supporting hangers 12 which may be connected 4with the rails 3. Anyother desired means, however, maybe employed for holding the channels orside bars 8 in place. Secured toV the side bars'S are luprights 14;sustained from the side bars by means of braces 15. Attached to theuprights 14; are side plates 16. Guide strips 17 are attached to theinner faces of the side plates 16 by means of securing elements 18. Theslots 19 in the side plates 16 through which the securing elements 18pass, preferably are elongated vertically as clearly indicated in Fig.4, so that the guide strips 17 may be adjusted vertically.

Connected with theside plates 16 near to their rear en ds are angle bars20 to which is secured a forwardly and 4downwardly inclined wall 21supporting a foot 23 held in place on the wall 21 by securing elements53. The slots 24 in thei'foot 22 through which the securing elements 23pass are elongatedvertically, so asto permit an adjustment ofthe foot22.

l' The receiverabove alluded to includes a reciprocating feederembodying la base plate 25 in slidable cooperation with the guide strips17 which are secured to the side'plates 16. Attached by means of asecuring element 29 to the forward4 end of the base plate 25 is a bar 26supporting a removable lip 27 held in place by a securing ,devicev 28,the construction being such that the lip may be renewed readily whenworn. Extended longitudinally of the base plate 25 and secured theretoare wear strips 30 which bear immediately upon the lower edges of theguide strips 17. Secured to the rear end of the member 25 is a plate 31held in place by securing elements 32, the plate 31 operating beneaththe lower end of the inclined foot 22.

At this place it may be noted that the foot 22 is so mounted on the wall21 that the foot may be raised and lowered to cooperate with the plate31, it being possible to adjust the guide strips 17 vertically so thatthey will coperate with the wear strips 30, and all of these elementsmay be detached and be replaced when worn.

Fixed to and depending from the base plate 25 of the feeder are anglemembers 33, the vertical flanges of which lie between rollers 34, thehorizontal flanges of which constitute tracks coperating with therollers, as shown best in Fig. 3. The rollers 34 are carried by axles 35supported in the channels or side bars 3. 1t will now be clear that whenthe feeder comprising the plate 25 and attendant parts is reciprocated,the plate slides to and fro on the rollers 34, the rollers constitutingan anti-frictional mounting for the plate.

Attached to the base plate 25 of the feeder are laterally offsetbrackets 36 carrying pins 37 which are mounted upon the base plate 25 ofthe feeder, as indicated at 38 in Fig. 3. The pins 37 support pivotally,the rear ends of pitmen 39 united by adjustable connections 40 with eyes41 pivoted on wristpins 42 carried by cranks 43 constituting a part of ashaft 44 journaled in bearings 45 secured to the forward ends of thechannels or side bars 8. Fixed to the shaft 44 is a sprocket wheel 46. Adownwardly inclined i chute 47 is attached to the forward ends of theside plates 16 of the receiver.

1n Fig. 1 of the drawings there is shown a bin 48 supported on posts 49,the upper ends 50 of which are connected to a conveyer supporting frame51. Braces 52 are connected at one end to the ports 49 and at theirother ends are connected to the side plates 16 of the receiver, asclearly shown in Fig. 1. Braces 53 extend between the braces 52 and theconveyer frame 51. Journaled for rotation in the lower end of theconveyer frame 51 (which projects into the pit 6) is a shaft 54. A shaft55 is journaled in the upper end `of the conveyer frame 51. Trainedabout the shafts 54 and 55 and operatively connected therewith is a beltconveyer 56 adapted to operate in the pit 6. Journaled in the conveyerframe 51 intermediate its ends is a shaft 57 connected by means of achain 64 with the sprocket wheel 46 on the shaft 44 whereby the feederplate 25 is actuated. A sprocket' chain 58 forms an operative connectionbetween the shaft 57 and a sprocket wheel 59 carried by the shaft 55.r1`he shaft 57 carries a sprocket wheel 60 connected by means of asprocket chain 61 with the shaft 62 of a motor 63 mounted on the support7.

In practical operation, the material dumped from a car is received bythe deflectors 4 and is directed between'the side plates 16 of thereceiver. WVhen the feed plate 25 is reciprocated, the material isadvanced into the chute 47, owing to the fact that the material tends tobank up on the inclined wall 21, and because the tendency of theinclined wall is to coact with the feeder plate 25 in advancing thematerial. From the chute 47, the material is received by the beltconveyer 56 and is carried upwardly by the belt conveyor and dumped intothe bin 48.

1When the motor 63 is operated, motion is transmitted to the shaft 57 bythe sprocket chain 61, and fromv the shaft 57, motion is.

transmitted to the shaft 55 and the belt conveyer 56 by the chain 58.From the shaft 57, motion is transmitted by the sprocket chain 64 to thesprocket wheel 46 on the shaft 44 and when the shaft 44 is rotated, thepitmen 39 will be actuated, the same imparting a sliding movement to thefeeder plate 25 through the pins 37.

Having thus described the invention, what is claimed is 1. 1n a deviceof the class described, a receiver comprising a bed frame; side platesconnected with the bed frame; a feeder mounted to reciprocate beneaththe side plates; an inclined end wall connecting the side plates; a footplate coperating with the feeder and slidable for adjustment on theinclined end wall; and means for connecting the foot plate adjustablywith the end wall.
